Compact and as light as 42 mm binoculars
The optical design prioritizes optimal compactness, featuring thinner lens elements, reduced lens diameter and minimized spacing between lenses. The magnesium housing ensures durability while keeping the weight low, allowing for comfortable, long-term use without fatigue.
Experience nature in all its splendour
The Ultra-High-Definition (UHD) concept features a special coating and an improved optical design that ensures the binoculars deliver the highest level of detail and reproduce colours with natural fidelity. This makes it possible to precisely identify the smallest features in the plumage and reliably distinguish between species.
SmartFocus Concept for an intuitive and precise handling
The SmartFocus concept makes it possible to focus quickly and precisely – without having to spread your fingers. The focusing wheel, perfectly positioned in the DoubleLink Bridge, offers the highest level of operating ergonomics, requiring only 1.4 turns from close focus to infinity and capable of being rotated precisely even with gloves on.
Bright images even in low light
With 90% light transmission, their large entrance pupil of 50 mm and the ZEISS T* multi-layer coating, you can clearly and precisely see details even in low-light situations and at dusk.
Comfortable viewing experience
The perfect ergonomics of the ZEISS SFL models enable quick and easy positioning of the eye and also provide comfortable and immersive viewing due to the large exit pupil. In addition, the improved eyecups provide an even better ergonomic feel and a smooth transition between the touch points, which are precisely defined and can be reached perfectly.
ZEISS T* Coating
ZEISS T* coating is a guarantee of the brilliant, high-contrast images which you will experience above all in adverse light conditions and in the twilight. Behind it, however, there is no specific formula for building up the layers. Instead, it is a technology that is constantly adjusted to suit new glass materials and requirements, which varies from lens to lens.
A clear view, whatever the weather
There are always exciting things to be seen in the world of nature – even in wet weather. This is why ZEISS developed LotuTec®. A coating for the lenses of binoculars and spotting scopes that enables a clear and unhindered view in all weather conditions.
